Description

Elastische Kupplungsscheibe Die Erfindung bezieht sich auf eine Verbesserung und weitere Ausgestaltung von elastischen Kupplungsscheiben, deren Band-, Seil- oder Laschenabschnitte zwischen den Anschlußbüchsen schräg zur Scheibenebene verlaufen.Elastic clutch disc The invention relates to an improvement and further design of elastic clutch disks, their band, rope or tab sections between the connection sockets run obliquely to the plane of the pane.

Die Erfindung besteht darin, daß zwischen den einzelnen Laschenanlenkaugen oder Seilschlingenenden an sich bekannte Absatzscheiben vorgesehen sind, die die schräg verlaufenden Anschlußaugen oder Schlingenenden in eine zu den Anschlußbüchsen senkrechte Lage umlenken.The invention consists in the fact that between the individual tab attachment eyes or rope loop ends known per se heel discs are provided that the inclined connection eyes or loop ends in one to the connection sockets redirect vertical position.

Durch die Scheiben nach der Erfindung mit einem bestimmten Durchmesser wird der Winkel der schräg verlaufenden Laschenabschnitte gegenüber den Büchsenachsen um bestimmte angestrebte Winkelgrade spitzer und damit die axiale Federwirkung der elastischen Verbindung um einen bestimmten Grad kräftiger. Umgekehrt wird die Drehelastizität der Kupplungsscheibe entsprechend weicher.By the discs according to the invention with a certain diameter becomes the angle of the inclined tab sections with respect to the bushing axes by certain desired degrees of angle and thus the axial spring action of the elastic connection stronger by a certain degree. The torsional elasticity is reversed the clutch disc is correspondingly softer.

Es eignen sich solche Kupplungen insbesondere für Schiffsschrauben antriebe mit Übersetzungsgetriebe, bei denen es an sich bekannt ist, zwischen Getriebe und Schiffsschraube elastische Kupplungen vorzusehen. Bei Konstruktionen, bei denen das Drucklager für die Aufnahme des Axialschubes der Schiffsschraube mit in das Getriebe eingebaut ist, werden die Schubkräfte durch die elastische Kupplungsscheibe hindurchgeleitet. Nun sind die bekannten Laschen- und Scheibengelenke verhältnismäßig nachgiebig, da deren wesentliche Bauelemente sich ausschließlich in der Scheibenebene erstrecken und daher unter den auftretenden Schubbeanspruchungen hauptsächlich auf Biegung beansprucht werden. Durch die Erfindung wird dieser Nachteil beseitigt.Such couplings are particularly suitable for ship propellers drives with transmission gears, where it is known per se, between gears and propeller to provide elastic couplings. In constructions where the thrust bearing for absorbing the axial thrust of the propeller into the Gearbox is built in, the thrust forces are generated by the flexible clutch disc passed through. Now the known plate and plate joints are proportionate compliant, as their essential components are located exclusively in the plane of the pane extend and therefore mainly under the shear stresses that occur Bending are stressed. This disadvantage is eliminated by the invention.

Es sind zwar auch schon elastische Kupplungsscheiben bekannt, bei denen als verbindende Elemente in Gummi eingebettete, um die Anschlußbüchsen herumgewickelte Seilschlingen dienen, die, weil sie alle aus einem einzigen Seilstück gewickelt sind, zwangläufig eine geringe Schräglage zur Drehachse der elastischen Verbindung oder zu den Achsen der zugehörigen Anschlußbüchsen einnehmen. Infolge dieser geringen Schräglage ist die Drehsteifigkeit dieser Verbindung unerwünscht hart und umgekehrt die axiale Schubelastizität zu weich.It is true that elastic clutch disks are also known at which are embedded in rubber as connecting elements and wrapped around the connection sockets Ropes are used because they are all wound from a single piece of rope are, inevitably a slight incline to the axis of rotation of the elastic connection or occupy the axes of the associated connection sleeves. As a result of this low In an inclined position, the torsional stiffness of this connection is undesirably hard and vice versa the axial shear elasticity too soft.

In der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt, und zwar zeigt Fig. 1 ein Laschengelenk in Seitenansicht, Fig. 2 eine Abwicklung von drei aufeinanderfolgenden Gelenklaschen nach Fig. 1 im Querschnitt, Fig. 3 einen Seilscheibenabschnitt mit abgewinkelter Seilschlinge.In the drawing, the invention is shown in an exemplary embodiment, namely, Fig. 1 shows a plate hinge in side view, Fig. 2 shows a development of three successive hinge straps according to FIG. 1 in cross section, FIG. 3 shows a Sheave section with angled rope loop.

Wie die Fig. 1 zeigt, besteht das Laschengelenk in üblicher Weise z. B. aus sechs einzelnen Gelenk laschen 1, die an ihren einander zugekehrten Enden mittels Büchsen 2 gelenkig miteinander verbunden sind. Der Aufbau dieser Laschen ist im Rahmen der Erfindung beliebig. Es bestehen diese in der Regel aus einem in einer elastischen Masse eingebetteten Band oder einer Natur-, Kunstfaser- oder Drahtseilschlinge, die entweder innerhalb einer Lasche in sich geschlossen liegt oder die sich über mehrere Laschen erstreckt. Auch können die Laschen an den Anschlußenden in an sich bekannter Weise mit auf die Büchsenenden aufgebrachte Scheiben od. dgl. armiert sein.As FIG. 1 shows, the bracket joint is made in the usual way z. B. from six individual hinge tabs 1, which at their ends facing each other are articulated by means of sleeves 2. The structure of these tabs is arbitrary within the scope of the invention. These usually consist of an in an elastic mass embedded tape or a natural, synthetic fiber or wire rope loop, which is either closed within a flap or which extends over extends several tabs. The tabs can also be at the connection ends in per se in a known manner with disks or the like applied to the bushing ends be.

Gegenstand der Erfindung ist, daß die einzelnen Laschen zwischen ihren Anlenkungen schräg zur Gelenkscheibenebene verlaufen, und zwar vorzugsweise im wesentlichen in Richtung der resultierenden R, die sich aus den auftretenden Tangentialkräften Pt und den Axialkräften Pa ergibt. Als Resultantenwinkel wurde in der Zeichnung ein solcher von 30° als Ausführungsbeispiel gewählt. Weiterhin ist es von Vorteil, die zwischen den Laschenanlenkungen vorgesehenen Abstandsscheiben 3 schwach ballig zu gestalten oder zumindest deren Randkanten abzurunden, um einen vorzeitigen Verschleiß der Laschen zu verhindern.The invention is that the individual tabs between their Articulations run obliquely to the joint disk plane, preferably essentially in the direction of the resulting R, which results from the tangential forces that occur Pt and the axial forces Pa results. The resultant angle in the drawing was one of 30 ° selected as an exemplary embodiment. It is also advantageous the spacer disks 3 provided between the link plate linkages are slightly convex to shape or at least to round their edges to prevent premature wear to prevent the tabs.

Man kann, wie die Fig. 3 zeigt, die gleiche Anordnung auch an Gelenkscheiben treffen, bei denen der Raum zwischen den Büchsen 2 mit einem elastischen Werkstoff 5, z. B. Gummi, voll ausgefüllt ist, wobei auch dieser Werkstoff mit Fasereinlagen od. dgl. versehen sein kann. In diesem Fall liegen die Seilschlingen oder -schlingenabschnitte 4, z. B. nach dem Vorbild der Laschen 1 in Fig. ?, abgewickelt in der Masse 5 eingebettet (Fig. 3 ) . Die angestrebte Kompensation kann durch eine entsprechende Wahl des Laschen- oder Seilschlingenwinkels beliebig abgestimmt werden. Sie wird um so größer, je spitzer dieser Winkel ist.As shown in FIG. 3, the same arrangement can also be made on flexible disks in which the space between the sleeves 2 is coated with an elastic material 5, e.g. B. rubber, is fully filled, and this material with fiber inserts od. Like. Can be provided. In this case, the rope loops or loop sections 4, e.g. B. after the model of the tabs 1 in Fig.?, Unwound in the mass 5 embedded (Fig. 3 ) . The desired compensation can be adjusted as required by a corresponding choice of the plate or rope loop angle. It becomes larger, the more acute this angle is.
